Bariatric Surgery is a group of Laparoscopic procedures done on morbidly obese patients for achieving and maintaining significant weight loss and marked improvement in obesity related illnesses.

Laparoscopic sleeve gastrectomy (LSG): ,a vertical gastrectomy that leaves a narrow gastric tube along the lesser curvature of the stomach, has been accepted as a primary procedure for morbid obese patients recently because of its simplicity and effectiveness. Several randomized trials also demonstrated that LSG has a similar efficacy of weight reduction comparing to Roux- en-Y gastric bypass (RYGB) at short- to mid-term.

Verical sleeve gastrectomy

Roux-en-Y gastric bypass (RYGB):Here stomach is converted into a small pouch and anastomosed to proximal intestine, thus bypassing greater part of stomach and proximal intestine, resulting in calorie restriction and malabsorption.

Roux-en-Y gastric bypass (RNY)

Laparoscopic Mini Gastric Bypass: Another important recent change of technique is from two anastomosis Roux-en-Y Bypass to single loop anastomosis technique, the laparoscopic mini gastric bypass(MGB). The elimination of one anastomosis may reduce operative time and decrease the possibility of surgically related complication.
